We present the measurement of the energy dependence of the boron flux in cosmic rays and its ratio to the carbon flux \textcolor{black}{in an energy interval from 8.4 GeV to 3.…
Search for ultralight dark matter from long-term frequency comparisons of optical and microwave atomic clocks
Takumi Kobayashi, Akifumi Takamizawa, Daisuke Akamatsu +8
We search for ultralight scalar dark matter candidates that induce oscillations of the fine structure constant, the electron and quark masses, and the quantum chromodynamics energy…
Higgs Portal Majorana Fermionic Dark Matter with the Freeze-in Mechanism
Junpei Ikemoto, Naoyuki Haba, Shimizu Yasuhiro +1
We consider a minimal model of fermionic dark matter, in which the Majorana fermion dark matter (DM) couples with the Standard Model (SM) Higgs field through a higher-dimen…
Efficient Dicke state generation in a network of lossy channels
Wojciech Roga, Rikizo Ikuta, Tomoyuki Horikiri +1
We analyze the generation of entanglement in a multipartite optical network. We generalize the twin-field strategy to the multipartie case and show that our protocol has advantageo…
Conditions for Suppressing Dimension-five Proton Decay in Renormalizable SUSY GUT
Naoyuki Haba, Toshifumi Yamada
The SUSY GUT is in severe tension with the experimental bounds on proton partial lifetimes because proton decay mediated by colored Higgsinos (dimension-five proton decay)…
Direct dark matter searches with the full data set of XMASS-I
XMASS Collaboration, K. Abe, K. Hiraide +29
Various WIMP dark matter searches using the full data set of XMASS-I, a single-phase liquid xenon detector, are reported in this paper. Stable XMASS-I data taking accumulated a tot…
Single-shot high-resolution identification of discrete frequency modes of single-photon-level optical pulses
Daisuke Yoshida, Mayuka Ichihara, Takeshi Kondo +2
Frequency-multiplexed quantum communication usually requires a single-shot identification of the frequency mode of a single photon . In this paper, we propose a scheme that can ide…
Search for Lepton Flavor Violating Decay at FASER
Takeshi Araki, Kento Asai, Hidetoshi Otono +2
FASER is one of the promising experiments which search for long-lived particles beyond the Standard Model. In this paper, we consider charged lepton flavor violation (CLFV) via a l…
Low-latency adiabatic quantum-flux-parametron circuit integrated with a hybrid serializer/deserializer
Yuki Hironaka, Taiki Yamae, Christopher L. Ayala +2
Adiabatic quantum-flux-parametron (AQFP) logic is an ultra-low-power superconductor logic family. AQFP logic gates are powered and clocked by dedicated clocking schemes using ac ex…
Neutron Tagging following Atmospheric Neutrino Events in a Water Cherenkov Detector
K. Abe, Y. Haga, Y. Hayato +301
We present the development of neutron-tagging techniques in Super-Kamiokande IV using a neural network analysis. The detection efficiency of neutron capture on hydrogen is estimate…
Asymmetric Mediator in Scotogenic Model
Kento Asai, Yuhei Sakai, Joe Sato +2
The scotogenic model is the Standard Model (SM) with Z_2 symmetry and the addition of Z_2 odd right-handed Majorana neutrinos and SU(2)_L doublet scalar fields. We have extended th…
Observation of Spectral Structures in the Flux of Cosmic-Ray Protons from 50 GeV to 60 TeV with the Calorimetric Electron Telescope on the International Space Station
O. Adriani, Y. Akaike, K. Asano +77
A precise measurement of the cosmic-ray proton spectrum with the Calorimetric Electron Telescope (CALET) is presented in the energy interval from 50 GeV to 60 TeV, and the observat…
Search for Cosmic-ray Boosted Sub-GeV Dark Matter using Recoil Protons at Super-Kamiokande
Kamiokande Collaboration, K. Abe, Y. Hayato +218
We report a search for cosmic-ray boosted dark matter with protons using the 0.37 megatonyears data collected at Super-Kamiokande experiment during the 1996-2018 period (SK…
A Few-shot Approach to Resume Information Extraction via Prompts
Chengguang Gan, Tatsunori Mori
Prompt learning's fine-tune performance on text classification tasks has attracted the NLP community. This paper applies it to resume information extraction, improving existing met…
Skeleton structure inherent in discrete-time quantum walks
Tomoki Yamagami, Etsuo Segawa, Ken'ichiro Tanaka +4
In this paper, we claim that a common underlying structure--a skeleton structure--is present behind discrete-time quantum walks (QWs) on a one-dimensional lattice with a homogeneou…
High-speed high-resolution optical correlation-domain reflectometry without using electrical spectrum analyzer
